Property managers manually re-key locks between tenants at $150-$300 per turnover

Every time a tenant moves out, property managers must re-key or replace locks on all entry points to ensure the prior tenant's copies cannot be used. For a 200-unit portfolio with 40% annual turnover, that is 80 re-keying jobs at $150-$300 each, totaling $12,000-$24,000 per year — plus the coordination overhead of scheduling a locksmith during the narrow turnover window. If re-keying is delayed even one day past move-in, the new tenant has a legitimate safety concern and the manager faces liability. This persists because traditional pin-tumbler locks require physical re-keying by a licensed locksmith, and smart lock adoption in rental housing is slow due to upfront hardware cost ($200-$400/door), tenant tech-literacy concerns, and lack of integration with existing property management software.
